Rails 5 mailer preview with Rspec

Question

I always get this error: Mailer preview 'user_mailer' not found

spec/previews/user_mailer_preview.rb

class UserMailerPreview < ActionMailer::Preview
  def contact_form
    UserMailer.contact_form("[email protected]", "John", "Hello World!")
  end
end

I tried to add:

config.action_mailer.preview_path = "#{Rails.root}/spec/previews"

but it didn't work.

Any ideas how to solve this problem?

I had the same problem and this thread fixed it. stackoverflow.com/questions/39204047/… — user847074, Commented Nov 10, 2017 at 0:11

Try moving the file to spec/mailers/previews/user_mailer_preview.rb.

Another option would be to change the path in environments/development.rb to:

config.action_mailer.preview_path = "#{Rails.root}/spec/mailers/previews"
